Radar multi-target data interconnection method

Abstract

The invention discloses a radar multi-target data interconnection method, which comprises the following steps of: (101) calculating characteristic parameters and a parameter table of a flight path of a plurality of detection targets according to radar echoes; (102) calculating random deviation of target observation according to a radar performance index requirement and a radar design state; (103) calculating a similarity coefficient of each detection target and a similarity coefficient of a target in the flight path according to the characteristic parameters obtained in the step (101) and a parameter list of the flight path; (104) introducing a detection target of which the similarity coefficient is less than that of the target in the flight path into a pre-interconnection queue, continuing the step (105), and otherwise, jumping to a step (106); (105) searching a detection target with the minimum similarity coefficient in the pre-interconnection queue, and interconnecting the detection target with the flight path; and (106) updating data information in the flight path parameter.

Description

technical field [0001] The invention relates to radar technology, in particular to a multi-detection target and track interconnection method applied to data processing. Background technique [0002] Radar is a device that uses radio technology to find targets and determine the spatial position of targets. Modern radars usually include two important components: radar signal processing system and radar data processing system. Parameter data (such as radial distance, radial velocity, azimuth, etc.) are then calculated for interconnection, tracking, filtering, smoothing, and prediction to form the track of the target. [0003] Among them, the interconnection of target data is to establish the relationship between the radar measurement data at a certain time and the measurement (or track) at other time. to determine if the measurements are from the same target and to determine the correct pairing of track and track. [0004] At present, there are "wave gate method" and "retriev...
